1 Claim. (6i. 215 31) This invention refers to bottles and more particulariy to a so-called non-dripping bottle. lit

has among its objects:

To provide a-bottle that will not allow the liquids poured from it, to run down the body of the bottle, when tipped to pouring position, but will cut the flow ed with a clean out;

To have a mouth on a bottle that will permit drops to be poured and counted, without the drops flowing down the side of the bottle;

To have a bottle adaptable for controlling the v dropping process from a bottle in pouring:

To have such an arrangement provided, and yet permit the bottle to be readily and conveniently manufactured;

To provide for the general control of liquids from bottles;

To have such provisions that they will be suitable for liquid containers of many kinds, in addition to bottles (so-called) specifically, and many other objects that will become apparent as the invention is more fully set forth.

The existing types of bottles used for contain= ing liquids oi various kinds, and particularly those of a medicinenature, have the dimculty oi causing liquids poured from them, to catch and flow vided with means'for giving a control of the how of liquid from it, which means may be at the era-- treme mouth or adjacent to it. flhe means is termed a non-drip feature and may be a part of the bottle material or added as an extra member to provide the desirable function. The use of this invention enables those using the bottles to measure drops or flow from the same with facility and accuracy, while at the time preventing the liquid flowing down the side of the bottle and spoiling-the label or appearance of the bottle.

In the drawing which illustrates by way of ex-= ample an embodiment of this invention:

Figure 1 represents a bottle having its neck arranged with an embodiment of this invention,

Figure 2 is an enlarged detail in section of the bottle neck indicated in Figure 1 and with various portions named for facile identification,

Figure 3 is a modified form partly in section showing the neck exterior at the drop break portion extended slightly,

Figure dis a form of neck provided with a modifled exterior drop-break portion.

Similar reference characters refer to similar parts throughout the drawing.

in the construction shown in the drawing, i, indicates in all the views the body proper of a bottle which has a typical shoulder 2 from which 3, a neck extends and terminates with a mouth plane 43'. Screw threads such as are found moulded on bottles using screw caps are shown at it, and the fender iiis provided for acting as a stop for the cap and other purposes. In Figure l there is provided in the mouth of the bottle, a

slanting or bevelled outflow l on the interior, to which is connected a barrel passage 8, and which is so arranged that it has an edge 9 that forms a restricting barrier to the flow of liquid from.

is preferably the bottle body. This barrier squared as indicated. In other figures, the similar parts are indicated with the same reference characters to assist in identifying them. In pouring the liquid from this bottle mouth in the usual manner, and holding it up so that the flow is very gradual and restricted, the barrier will afiord some resistance and split the flow stream causing it to readily break into drops. As the broken stream reaches the bevel, it accelerates and as it reaches the mouth plane, it cuts the 1.

drops oil and they flow off without any tendency to run down the bottle neck and drip thereon, which is particuiarly prevented by the elongated end portion it that extendsexteriorly above the screw threads and is of less diameter than that I- or? the screw threads.

' The action of this mouth on the bottle is peculiar as it definitely makes a non-drip feature when liquids are poured through it, and while there is a cutting function on the dropsthat for this reason various other constructions are indicated in the difierent figures to meet these conditions. The other figures are seli-explana tory.

The various containers may be made of glass or similar vitreous materials, or 011 other materials suitable for liquids and liquid containers, as are now used or to be used in the future. Where the device that is outlined in this invention, is made separable, such may be made of any suitable material and attached in any convenient manner when placed in the bottle.

The normal pouring position of bottles is that of a horizontal'but slightly tilted, and in such cases, the flow may be made to come out slowly, until there is a drop action, and the dropping can be controlled, drop by drop with the containers outlined in this application, and there is a complete absence of running-down of the stream on the side or body of the container.

The general action of drip-less feature of this invention operates as followsz-Refe'rring to Figure 2, the bottle is tilted until the liquid in v the bottle flows from the barrel passage 8, passing over point 80, and along angular pouring lip I, to the edge 8|. Capillary attraction then attaches the fluid to the face 82. The set-back 83 then prevents the fluid from contacting the elongated portion lll. This naturally prevents the fluid from flowing to the right angular rise 84 and threaded portion 5, thereby preventing the where it overlaps, and is designated at 8|, 82 and 83 is termed a flange. The recess at 83 and 84, making the neck of the bottle restricted in diameter is termed an annular groove. The space between the flange and the plane surface at 84 and is termed a drop-break because the distance is sufficient to avoidpermitting the drop of liquid to bridge over it and flow down the remainder of the outside surface of the bottle neck. The angular lip 1 and face 4, by tending to bring the drop of liquid back into the bottle, is termed a drop slide, especially when the .drop is not positioned sufliciently to fall over the edge 82 in the manner already described.

Many experiments have been made in the matter of this invention by the applicant, covering many types of bottles, andmany diil'erent liquids, and it has been found that existing conventional types of bottles do not provide this feature of non-dripping, so-called, and where the insertion of a make shift device for insertion in the bottle neck has been used, such have not proven to be of practical serviceability, as have 5 been heretofore provided. It has also been unsatisfactory from a manufacturing point of view to avoid the construction of a bottle with this function that has not the arrangement homogeneously embodied in it, but since in the past 10 there was no-such bottle provided with these features, such have not been heretofore embodied by bottle manufacturers, especially those of a vitreous nature. The features are shown incorporated in the bottle and afford the functions that enable the manufacturers to provide same in it.

While several types of construction of this invention have been indicated in the drawing, it is not desired to limit this application for patent to them, or in any other way, other than limited by the prior art, as it is appreciated that other forms of construction might be made that would use the same principles and come within the scope of the appended claim. I

I claim: In a bottle neck, the combination of a neck proper with an interior barrel or throat formed by the interior walls thereof, a mouth or orifice portion extending from the said walls having walls angularly disposed with respect to and connected with the walls of the throat, a mouth plane disposed at right angles to the axis of the neck and extending outwardly therefrom to form the face a flange at the end portion of the neck, a peripheral wall around the mouth plane and extending perpendicularly down therefrom to form the edge wall of the flange and away from the exterior wall of the throat, said peripheral wall being connected at right angles to the under surface wall of the flange, providing a set-back plane parallel to the mouth plane and inwardly limited with respect to the bottle neck by the exterior wall of the throat portion, said exterior wall of the throat portion being disposed. at right angles thereto and downwardly forming a restricted portion of the neck and spacing the flanged portion from the 'main body portion of the neck, the said mainv portion of the neck being enlarged and provided with an upper surface plane at right angles to the exterior wall of the restricted portion, substantially as described.
